Specification forming part of Letters Patent No. 47,394 dated April 25, 1.865; antedaied April l5, 1865. i h

To all whom it mug concern; A

Be it known that I, JOHN CI-IILCOTT, of- No.

in Preparing Grain for Distillation; and I do hereby declare that the following is a full,

clear, and exact description of the same, refl erence being had to the accompanying drawing, forming part of this specification, said drawing representing a verticalsection of an apparatus which may be used in carrying'on my. invention;

The object of my invention is to prepare grain, more especiallycorn, for distillation in such a manner as to enable it to form a more intimate mixture with the water in the mashtub; and to this end itconsists in first subjecting the grain to the action of steam-Which saturates and swells it and bursts the, skin, and afterward passing it between rollers and crushing-itto a pulp.

To enable others to prepare grain for distillation according to my invention, I will pro ceed'to describe the same with reference to the drawing.

A is a tight vessehof a convenient size, pro vided with a strainer, a. On top of said vessel is a man-hole, e, throughwhich. the corn is placed into the vessel fitted with a steamtightilid.

'dis a perforated central pi pe, ilirough which steam is admitted into the vessel A.

b is a door so situated as to allow the corn to pass out of the vessel A into the hopper B and between the rollers G C. These rollers may be made hollow and lieated by steam, and are set injmotion bygears 'E E.

,0 is a pipe which carries off the water of condensation passing through the strainer a. The operation is as follows: Corn or other grain, being placed into the vessel-A through thc opening e,ris subjected to the action',of

steam admitted through the perforated pipe (1. The steam saturates and swellsthe corn and bursts the skin, thus separating the lat: ter from the inside, When it i's steamed long enough to become very soft, the grain is let out through the door 12 into the'hopperB, from which it passes between two rollers, G, and is thereby thoroughly crushed toa pulp,which will readily mix with water, when it is introduced into the mash-tub. Corn thus prepared for distillation is far superior to when prepared in the old way of grinding the same,- as theskin being entirely separated allowsthe interior of the grain to be brought to asoft pulpy state and mixed very intimate lywith thewater in the niashtub, giving a greater yield of spirit.

What I claim as my invention, and desire to secure by Letters Patent, isp 1; The process of preparing grain for dis tillationby steaming and crushing it between rollers, substantially as herein described?- '2. The combination of the steaming-vessel A, perforated pipe (I, hopper B, and rollers C O, substantially as and for the purpose set forth. i
